2 Claims. (Cl. 21540) This invention appertains to bottle and jarstoppers and more particularly to a reuseable closure for effectivelysealing a bottle or other container irrespective of any internalpressure therein.

Much difficulty is now being experienced in tightly sealing bottles andother containers due to the scarcity of war critical materials, such asI metals, and it is therefore one of the primary objects of my inventionto provide a novel stopper or closure, which can be formed fromnon-critical war materials, (such as glass, plastic and the like) forlocking engagement with the bottle or other container.

Another salient object of my invention is to provide a bottle stopper orjar closure, in which the stopper or other closure and the bottle or jarare provided with like wide, mating, sealing and closure thereforconstructed with my invention.

Figure 3 is a top, plan view of the jar closure.

Figure 4 is a detail, fragmentary, perspective view of a tool which canbe utilized for opening and closing the fruit jar.

Referring to the drawing in detail, wherein similar reference charactersdesignate corresponding parts throughout the several views, the letter Bgenerally indicates a bottle, and S my novel. stopper therefor. I

The bottle B can be of any desired size, shape or character, and asillustrated the same includes a neck 5 having the usual annular head orlip 6 onits upper end. In accordance with my invention the interior ofthe neck at its upper end faces with cooperating means in the stopperand 3 bottle, orclosure and jar, for drawing said faces into intimatesealing engagement, whereby loss.

of the contents due to leakage or spoilage is prevented.

A further important object of my invention is to provide a bottle or jarneck having a reversely curved stopper seat extending from the lip ofthe bottle or jar inwardly into the neck a material distance and astopper adapted to fit in said neck having its outer surface shaped tostopper consists of a solid circular body [I having seat when thestopper is inserted in the neck and turned a portion of a revolution.

A still further important object of my invention is to provide a bottlestopper or jar closure of the above character whichis durable andefficient in use, one that is simple and easy to manufacture, and onethat can be placed upon the market at a low cost.

With these and other objects in View, the invention consists in thenovel construction, ar-

rangement, and formation of parts, as will be hereinafter morespecifically described, claimed, and illustrated in the accompanyingdrawing, in which drawing:

Figure 1 is a fragmentary, side elevational View, partly in section, ofa bottle neck showing my novel stopper connected therewith.

Figure 1a is a fragmentary, detail, sectional view of the bottle neckillustrating one of the locking grooves formed in the stopper seat.

Figure 2 is a fragmentary, side, elevational view, partly in section,showing a preserving jar is provided witha novel seat I forthe stopperS.

As illustrated, the seat I takes substantially the fform of a reversecurve in cross section, similar to an ogee curve; Hence, in effect, thereversely curved seat I forms a continuous sealing surface fromthe upperface of the lip 6 down into the interior of the neck for a considerabledistance.

By referring to Figures 1 and la, it can be seen that the seat Iprovides upper and lower annular shoulder seats orv surfaces 3 and 9respectively with an intermediate sealing surface Ill.

, The stopper S; can be formed from any desired material and can beadvantageously molded from glass or other desired plastic material. The

an annular peripheral bead l2 which is adapted to seat against the outersurface of the bottle lip 6. Below the annular head [2, the stopper Shas formed. on its outer surface the reversely curved face l3 whichcorresponds identically with the seat I so that when the stopper isinserted in the neck the curved surface l3 will intimately contact withthe seat I throughout its entire area. The lower face of the stopper ispreferably of a convex form. r e

The curved face l3 of the stopper has formed thereon at diametrioopposite. points radially extending locking cam lugs I4. It is to benoted that the upper faces of the lugs 14 are inclined or of a wedgeshape.

v The interior of the bottle neck is provided at diametric oppositepointswith bayonet slots in accordance Attention is called to,

the stopper will be held on its seat by the engagement of the cam orwedge lugs I4 with the walls of the grooves and hence the stopper cannotbe blown off of its seat by internaipressurein the. bottle.

. In Figures 1 and lo I have-shown the features of my, inventionincorporated with a bottle neck jar neck with the reversely curved seata wide, sealing surface of great area is provided and this gives apositive seal.

If preferred a sealing gasket 30 can be placed between the flange 21 ofthe closure C and the jar neck. If desired the gasket can take acircular shape in cross section and the lower face of the flange 21 canbe provided with an annular groove to receive the gasket.

For convenience in turning the closure C, the same can be provided witha cross shaped depressiorrill and a tool 32 having a cross shaped head33. can beprovided- The head 33 can be inserted in the depression 3! andupon rotation of the tool the closure can be conveniently turned ineither direction;

I From the foregoing description, it can be seen and stopper andobviously the various features of my invention can be incorporated withvarious types of closures for other containers. In Figures 2 and 3 Ihave shown the principles of my invention utilized in a fruit or similarjar. Re-

ferring to these figures theflruit jar is indicated by the referencecharacter. J and my novel. closure by the reference character C.

The jar J includes a body 20 of any preferred size and configurationhaving the neck 2! on its. upper end. The interior of. the neck isprovided with the reversely curvedv seatZZ and. this seat is of the sameshape and configuration as the seat 'I previously described and henceupper and lower annular shoulder seats 23 and 24 are respectivelyprovided with an. intermediate curved face therebetween. The innersurface of the neck can be. provided, atquarters, with the bayonet slotsorgrooves 25 and these slots or grooves 25 are formedbetween the seats23 and The jar closure C includes a body 26 having formed on its upperend the annular outstanding flange 21 which is adapted to extend overthe seat. 23 and over the outer lipof the neck. The body of the stopperC, below the flange, has its outer surface. provided with the reverselycurved face 28 which corresponds directly with the shape of the curvedseat 22 forv intimate sealing engagement therewith. The bottom surface.of the stopper 0- is also preferably of a convex form.

Thebody of the. closure below the flange 21 is provided, at quarters,with radiallyv extending cam orv wedge shapedlocking lugs 29 which areadapted to be inserted in the bayonet slots or rooves 25.

In. use of my closure the jar is filled in any approved. manner afterwhich the closure 0 is inserted in the jar neck with the cam or wedgeshaped lugs. inserted in the bayonet slots. The closure is now given aslight turn so as to move the wedge shaped lugs in the right-angularportions. of the bayonet slots or grooves. and the contacting of thewedge or cam lugs with the walls of the grooves will forcibly bring downthe closure within thejar neck so that the curved seal.- ing.v face 28thereof will be brought into tight engagement with the curved seat 22in-the jar.

By forming the stopper and. closure in the manner described and byproviding the bottle and that I have provided an exceptionally simpleand durable closure which can be effectively formed from non-criticalwar materials. Obviously the stoppers and closurescan be continuouslyreused and as the same are formed tromglass or plastic, cleaning thereofis. easily effected.

Changes in details. may be made. without departing from the spirit orthe scope of my in.-

vention,. but what I'claimas new is;

l. The combination with. acontainer having a neck provided with aninterior. reversely curved closure seat, said seat extending. from theouter surface ofv the neckinto the. interior of said neck and definingan. upper annular. shoulder seat and a lowerv annular shoulder seat. of.less. diameter than the upper annular shoulder seat and an intermediateconnecting curved surface, of a closure removably fitted in the neck.having a curved surface shaped to correspond to said seat for contact.therewith, said closure and neck having cooperating cam Iugsand groovesfor drawing the curved surface of. the closure into tightseali'ngcontact with the upper and lower shoulder seats and the intermediatecurved surface of. the

neckv upon the insertion' of. the cam lugs in the grooves and theturning of the closure.

2. The combination with a bottle having a neck provided with anannularlip and an interior annular seat extending from said .lip into the neck,said seat: having a reverse. curve in cross section. defining. upperandlower annular shoulder seats andan. intermediate connecting curvedsurface, of a stopper .insertable in said neck including a body providedwith an annular bead and a reversely curved annular surface below saidbead. for contacting with the interior annular seat, said bead engagingthe outer face of the lip, the seat having formed therein in theintermediate curved surface between the upper and lower shoulder seatsL-shaped grooves, and radially extending cam lugs formed on the curvedsurface of the stopper for insertion in said grooves, whereby uponturning of the stopper and movement of the logs in the lower ends of thegrooves, the curved surface of, the. stopper will be drawn into intimatesealing engagement with the upper and lower shoulder seats and theintermediate. curved surfacev andthe head into engagement with the lip.
